On the day the 15-year statute of limitations expired on a high profile serial murder case that claimed the lives of 10 women, a family member of the victim throws himself off the building in front of the detective in charge of the case. 2 years later, a man called Lee Du-seok publishes a book titled “Confession of Murder” claiming responsibility for the murders that took place 17 years ago. His book becomes a bestseller because of the author’s charming looks and his vivid depiction of the crime.
The detective and the self-claimed murderer meet face to face on a television debate show. Detective Choi maintains that Lee is nothing but a con artist posing as the murderer for the fame alone. Detective Choi renews his search for the ultimate truth.
